VENTILATOR.

SPECIFICATION forming part of Letters Patent N 0. 792,990, dated June 20, 1905.

Application filed April 5, 1904. Serial No. 201.692.

To all whom, it may concern:

Beit known that I, JAMESHOUGH, of the city of Guelph, in the county of Wellington, in the Province of Ontario, Canada,have invented certain new and useful Improvements in Ventil-ators, of which the following is a specification.

My invention relates to improvements in ventilators particularly adaptable to windows; and the object of the invention is to provide a simple device which will serve to thoroughly ventilate an apartment without creating a draft; and it consists, essentially, of a sleeve having an open side communicating with an opening in the sash and a tube rotatably adjustable in such sleeve and provided with a slot designed to be brought opposite the opening in the sleeve to ventilate the apartment,"

the tube and sleeve and parts being constructed and arranged in detail, as hereinafter more particularly explained.

Figure l is a perspective view of a portion of a window-sash, showing the location of my improved ventilating device. Fig. 2 is asectional perspective view, broken away, showing the ventilating device closed. Fig. 3 is asimilar view showing the ventilating device open. Fig. 4 is a detail of the open-sided sleeve. Fig. 5 is a detail of the tube. Fig. 6 is a detail of the turning-knob. Fig. 7 is a crosssection showing an alternative means of turning the tube.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is a sleeve provided with a flat side A, the longitudinal opening a therein and lugs a, by which such sleeve is fastened to the window-sash B opposite the opening [2, extending through the sash and of the same width and length as the opening a in the sleeve.

C is a deflecting-plate extending outside of the sash and designed to shield off rain and to break a direct wind from the opening Z). The sleeve A is provided with a circumferential slot a located, preferably, in the center of the same.

D is an open-ended tube, which is provided with the perforations (Z, extending on each side of the sleeve A, and a central slot cl of substantially the same length and width as the opening a in the sleeve.

E is the turning-knob, which is secured to the tubeDby means of the screw 6, extending through from the inside of the tube into the knob. It will be noticed that the knob E has fiat sides e, which abut the sides of the slot a",

and thereby prevent the knob from becoming unfastened. The knob itself also serves prevent longitudinal displacement of the tub D within the sleeve A. By turning the knob E so as to throw the tube into the position shown in Fig. 3 the air passes through the openings 6, a, and (Z into the tube and out through the opening (Z and ends of the tube.

It will be noticed that when the tube D is set to provide for ventilation the perforations d are located on the inside of the tube, and consequently the air passing thereth rough into the room or apartment strikes the sash, and thereby all danger of draft is avoided. The openings at the end of the tube necessarily throw any air laterally, and this also prevents any draft in the room.

In Fig. 7 I show aspiral spring F, attached to the turning-knob E and to an eye secured to the sash, and I also show a cord f. This spiral spring and cord are used when the ventilating device is placed at the top of the top sash of the window, and it willbe readily seen that to open'the ventilator the cord has to be pulled down and fastened in any desired position, so as to hold the ventilator open. Upon the release of the cord the spring F restores the ventilator into the closed position.

Although I show my device as applicable to window-sashes, it will quite readily be understood that it will be applicable to walls of apartments and various other places where it is necessary to provide for ven tilatioh. Again, it will be readily understood that my device is readily applicable to railway-cars, trolleycars, hospitals, schools, buildings, dwellings, and for many other purposes which it is not necessary here to mention. It will also be understood that not only may itbe applied at the lower part of an apartment, but itmay be with equal facility applied to the upper part or in any position desired.

In devising this ventilator I have constructed it so that the side tubes D are intended to be used as a means for lifting the window, thereby making the ventilator not only a ventilator, but also a window-lift.

Although I describe in this specification only one sleeve, it will of course be understood in wide Windows that I mayprovide two or more s1eeves,and the tube would necessarily be made long enough so as to extend through all the sleeves.

What I claim as my invention is- 1. In combination with a sash or wall having an opening therein, a sleeve having an opening adapted to be located opposite the firstmentioned opening and having a circumferential slot, a tube extending through the sleeve and having its ends projecting beyond each end thereof, saidtube having an opening corresponding to the opening in the sleeve the projecting portions of said tube also having a row of perforations outside the sleeve and a BEST AVAlLABLE COP knob extending through the circumferentii slot of the sleeve and being connected to the tube for turning the same.

2. In combination with asash or wall having an opening therein, a sleeve having an opening adapted to be located opposite the first mentioned opening and having a circumfer tial slot, a tube extending through the slet and having its ends projecting beyond each end thereof, said tube having an opening corresponding to the opening in the sleeve and projecting portions of said tube also having a row of perforations outside the sleeve and in a line with said opening, and a knob extending through the circumferential slot of the sleeve and being connected to the tube for turning the same.

JAMES HOUGH.
